Now, with a governing majority, they've had to come up with a replacement plan - a task that has proved much more challenging than they may have imagined.

Here's a look at some key differences between the existing law, informally known as Obamacare, and the American Health Care Act, crafted by the Trump administration and Republican leadership in the House of Representatives.

Individual mandate

Obamacare: All Americans are required to have health insurance or pay a tax penalty.

Republican plan: The mandate is repealed, but individuals who forgo health insurance for more than 63 days must pay a 30% surcharge on their insurance premiums for a year.

Employer mandate

Obamacare: Companies with more than 50 employees are required to offer health insurance or pay a penalty.
